SPECIFICATION forming part of Letters Patent N o. 714,280, dated November 25, 1902.

Application filed March 3| 19024.

To alf/ZZ whom it may concern:

Be it known that I, GRANVILLE E. CHAM- `PLIN,residin g at Lau rel,in` the county of Cedar companying drawings and descriptions.

Figure 1 shows a top View, with portions removed, of a weeder embodying my invention. Fig. 2 shows a side view of my weeder with a portion broken away. Fig. 3 shows a rear view of the weeder-frame as detached, while Fig. 4 shows an end view ofthe supporting- `axle as used in `my invention.

My invention embodies, essentially, a supporting-axle C, a detail of which is shown in Fig. 4, which is bent approximately A-shaped i and provided below with the spindles c, adapted to receive the supportingfwheels 4. This axle below is strengthened by the transverse bar 6, secured by means of thebolts 5. Secured to this axle C is a carrier-bar A, which is secured to the highest portion ofthe axle C by means of the bolt 2, as is disclosed in Fig. 2. The bolt 2, which passes through the upper portion of the axle C, is also used to secure the toothed rack-bar. E, which is addii tionally secured bymeans of the bolt 3, as

disclosed in Fig. 2.`

This ycarrier-bar in the rear is provided with a suitable operator-seat B, securedby the bolt 1, as is disclosed in Fig.

` 1, the operator in riding upon this weeder placing his feet either upon the transverse brace-bars D, which diverge from the carriery bar and thenextend parallel therewith a suitable distance and then curve downward and are secured to the axle C by means of the bolts 5, which are also made, it will be seen,

Serial No. 37,329. (No model.)

to do service in supporting the transverse bar 6, as disclosed in Figs. 1 and 4. Approximately centrally'and above this carrier-bar is provided with a suitable ear 10,-below which is revolubly held a transverse rock-shaft F, which rock-shaft is given further support by means of the bearings 7, which are provided with downwardly-extending ears S, which stride the brace-bars D and are secured by means of a suitable pivota to the adjacent brace-bar D, as disclosed in Fig. 2. At each end this rock-shaft F is provided with a forwardly-extending hanger 15, from which depends a. chain 16, while approximately centrally this rock-shaft is provided with the lever 13, which is adapted to work adjacent to the toothed rack-bar E, so that said lever is normally in engagement with said toothed rack-bar and locked behind one of the teeth of the same. By this means the rock-shaft F may be adj ustably held in any suitable position.

Pivotally secured below the carrier-bar A is a tongue I, which tongue is provided with an upwardly-extending hook 35, engaging the ear 34, so that the tongue I is removably seycured to the carrier-bar A. This tongue I extends forward a suitable distance and is provided with the usual neck-yoke and upon the rear has secured to it two transverse frame-bars H H, positioned a suitable distance apart, as is disclosed in top view in Fig. 1, and these bars are` held by means of the bolts 39, one of which is shown in detail in Fig. 3. These bars extend outward a suitable distance and at each end support a rock ing tooth-frame, to which are secured gangs of weeder-teeth b. These teeth are arranged in staggered relation, as shown.

At the end each transverse frame-bar H is provided with a bolt 20, and loosely working about the ends of these transverse frame-bars is a swinging yoke, comprising the lowerhorizontal member 18, provided at each end with a loop 19 to encompass the ends of the transverse frame-bars, as is disclosed in Fig. 2, the bolt 2O acting as a horizontal pivot for this yoke 13. Secured below to each yoke are the transverse angle-bars 21, 23, and 25,which are strengthened by means of the transverse bars 24 24, as disclosed in Fig. 1. From these ICO angle-bars 21, 23, and 25 curve horizontally rearward and then vertically downward a plurality of spring-teeth b, which are made of wide fiat material, such as steel, and have their lower ends formed into four-cornered y spike-shaped terminations e, as is disclosed in Fig. 2, one sharp edge of each tooth c being presented to the forward advance of the machine. To prevent these rocking toothro frames from racking or rocking sidewise, I secure to said member 21 at each end a cross member or bar 24, which bar is then carried backward and upward and, secured, preferably, to the bolt 20, securing one end of the T5, yoke, while extending from the rear or last bar 25 and the end bar 24 is a second strengthening-rod 36, carried forward and upward and in turn secured to the bolt 20, supporting the yoke at its forward end. The hangerzo chains 16 are next secured to a suitable eyelet 17, referring now to Fig. 2, preferably fixed to the horizontal yoke member 18, so that the tongue is held suspended, approximately centrally, by means of the hook and z 5 eye 35 and 34, while the rear end supporting the tooth-gangs is held by means of the chain 16, which is secured to the hanger and shaft F, which shaft in turn is locked in a suitable position by means of the lever 13, so 3o that the teeth can be raised or lowered'by means of this lever 13.

Secured to the forward transverse framebar H are the staples w, from which extend suitable pulleys or sheaves z, over which 3 5 passes a chain W, secured centrally by means of the bar g, and to the end of each chain is secured a singletree h, as is shown in Fig. 1. From this it will be noticed that I provide, first, a sulky-frame, comprising the trans- 4o verse shaft F and the carrier-bar A, to which is detachably and adjustably secured the tongue carrying the teeth-gangs, as disclosed.

To the frame is further permitted a rocking movement in a vertical plane, while the 45 whole of the teeth-frames may be raised and lowered.

In Fig. 3 I have shown the location of the strengthening-rods 36 and 31 in connection with the bolts and 32, secured to the trans- 5o verse members H in supporting the same. Brace rods or bars are attached at one end to the bar A and at their opposite ends to members H.

Having thus described my said invention,

what I claim as new, and desire to secure by United States Letters Patent, is-

1. In a weeder, the combination with a wheel-supported carrier-bar, a rock-shaft secured to said carrier-bar, a tongue movably secured to the forward end of said carrier- 6o bar, transverse frame-bars secured to the rear end of said tongue, pivotally-held yokes secured to the ends of said transverse framebars, toothed bars secured to said yokes, a plurality of rearwardlyand downwardly curving teeth secured to each of said toothed bars, and means to connect said toothed bars to aforesaid rock-shaft, as and for the purpose set forth.

2. The combination with an approximately 7o A-shaped supporting-frame provided with two supporting-wheels, a carrier-bar secured to the uppermost end of said supportingframe, an operator-seat at the rear end of said carrier-bar, an eyelet at the forward end of said carrier-bar, brace-bars curving upward and inward, extending from aforesaid supporting-frame and being secured to the forward end of said carrier-bar, a rock-shaft, bearings supporting said rock-shaft secured 8o to aforesaid carrier-bar and to said bracebars, an adjusting-lever secured to said rockshaft, terminal hangers extending from said rock-shaft provided with depending chains,

a tongue pivotally secured near oneend to the ear of said carrier-bar, two transverse frame-bars secured to the rear end of said tongue, a pivotally-held yoke secured to the ends of said frame-bars, a plurality of anglebars secured to said yokes, a plurality of 9o rearwardly and downwardly curving teeth secured to each ofsaid angle-bars, said teeth being in a staggered position, aforesaid chains being connected to said yokes all arranged,

so that said angle-bars will be permitted a rocking movement in a vertical plane at right angles to the chains of the machine, said frame members supporting aforesaid teeth being permitted upward and downward adjustment by virtue of said rock-shaft, as has been set forth.

In testimony whereof I have affixed my signature in presence of two witnesses.

GRANVILLE E. CHAMPLIN.
